Kalshi Streams Full Order Books via DoubleZero

1 reports · First detected 2026-08-13 · Last active 2026-08-13

Kalshi operates a US-regulated event-contract exchange where institutional traders use real-time order-book data to assess prices, liquidity and market depth. DoubleZero runs a dedicated fiber network designed to distribute data with more predictable latency than the public internet, infrastructure that could help market makers respond faster and quote tighter spreads as prediction markets attract more professional trading firms.

Kalshi said on Aug. 13, 2026, that it became the first prediction market to stream complete Level 1 and Level 2 order books through DoubleZero. Institutional clients can receive top-of-book quotes and depth across price levels directly, instead of reconstructing the book from incremental API updates. The companies did not disclose pricing or other financial terms for the service.

The Backstory

The history behind this event
Kalshi Facilitates First Large Institutional Prediction-Market Block Trade2026-04-28 · 2 reports · similarity 0.82

Kalshi is an event-contract exchange regulated by the U.S. Commodity Futures Trading Commission, with contracts settling according to the outcomes of specified events. Greenlight Commodities has brought an NFA-registered framework for privately negotiated trades and centralized clearing to prediction markets. This allows institutions to hedge or invest with defined risk around individual events such as carbon prices, marking a significant step toward a more institutionalized market structure.

On April 27, 2026, Greenlight Commodities announced that it had brokered the first large institutional over-the-counter trade on Kalshi, with a Houston-based environmental hedge fund and Jump Trading Group on opposite sides. The trade was worth a six-figure dollar amount, but the exact value was not disclosed. The contract was linked to the settlement price of California’s 47th joint carbon allowance auction on May 20. Bernstein described the transaction on May 4 as a milestone in the market’s institutionalization.
